Section II. DESCRIPTION AND DATA
1-4.
Description
The amphibious lighter (LARC LX), hereafter referred to as LARC (figs. 1-1 and 1-2) is an amphibious transport vehicle
used to transport wheeled and tracked vehicles and general cargo from ship to beach and inland transfer points. It can
be deck loaded on a larger vessel or carried in the well deck of an LSD for transportation to overseas destination. The
LARC is a 4-wheeled lighter capable of transporting 120, 000 pounds of cargo from an offshore supply vessel through
heavy surf; under favorable conditions the LARC can transport 200, 000 pounds. In land operation, each wheel is
independently driven by one of the four engines. In marine operation, the port propeller may be driven by either or both
port engines and the starboard propeller by either or both starboard engines. If you need a detailed description of any
component of the LARC, ask your supervisor to see TM 5-1930-203-20.
